Badger Meter COIN-NW - Manual (Page 7)

When installing chemical tee seals tighten cap screws uniformly in a “star” pattern
to avoid localized stresses on the gaskets.
The ANSI flanged taps seals require a backup flange rated for the same type
and class as that on the COIN element. Backup flanges with bolts and nuts are
generally offered as an option to the transmitter and are not supplied with the
COIN element. Again, observe recommended torque specifications for the type
and class being used.
